Hi! Im trying to decide which printer is best. I think Canon pixma ip5000 or epson r800 are the good choices but i heard some complaints about epson and macs.. I do a lot of photo and drawing prints and i want to be able to use the printer in both iMac G5 and pc (i have a home network). the hp 8450 also recieved good reviews. can you please help to choose? thanks!
